Energy Storage System(ESS)

The energy storage system (ESS) is a system that stores electricity in a storage device (battery) and supplies it
when power is needed to increase the energy efficiency and stabilize the power supply system.
Increased energy efficiency through the convergence of the ESS and PESS-EMS
Processing, analysis, and control of energy information
Provision of diverse electric power service information through the website and smartphone application
Time-of-use (TOU) pricing and charging and dischargingschedule based on a demand-response program
Peak load management / Frequency adjustment / Improved power quality / Voltage adjustment and management

Application Effects

Reduction of electric charges through reduction of peak load

Additional reduction of electric charges during maximum load hours

Convenience in operation through different electric charges at different times

50% discount rate applied to ESS charging rates at night
